Mentalizing mediates the relationship between psychopathy and premeditated criminal offending in schizophrenia: a 6-year follow-up study.

PURPOSE

Research has shown that schizophrenia augments the risk for criminal behaviour and variables both defining- and related to schizophrenia, increase criminal offending. Premeditated criminal offending is considered a severe form of criminal offending, however, very little is known about what predicts future premeditated criminal offending in schizophrenia.

METHOD AND MATERIALS

In this 6-year follow-up study we explored which factors underlie future premeditated criminal behaviour in a sample of patients diagnosed with schizophrenia ( = 116). We also investigated if a specific mentalizing profile underlie part of the variance of premeditated criminal offending.

RESULTS

Results showed that psychopathy underlie future premeditated crime in schizophrenia, and that a specific mentalizing profile, comprised of a dysfunctional emotional and intact cognitive mentalizing profile in relation to others, mediated parts of the relation between psychopathy and premeditated criminal offending. Finally, our results indicated that patients with schizophrenia with a specific mentalizing profile (see above) engaged in premeditated criminal behaviour earlier during the 6-year follow-up period compared to patients with other mentalizing profiles.

CONCLUSIONS

Our findings suggest that mentalization should carefully be inspected in patients with schizophrenia in relation to future premeditated offending.
